The Hg concentration of anodic oxide films on Hg1-xCdxTe and its change after heat treatment were investigated by using 40 MeV-O5+ backscattering. Heat treatment in a vacuum for 60 min was performed at various temperatures up to 350 and 400 Â°C, respectively, for the samples with x=0.19 and x=0.32. A significant Hg content in the as-grown anodic oxide was found in accordance with the recent result of C. M. Stahle, D. J. Thomson, C. R. Helms, C. H. Becker, and A. Simmons [Appl. Phys. Lett. 47, 521 (1985)]. The Hg in the film gradually decreased with increasing heat treatment temperature up to about 290 Â°C and rapidly disappeared above 290 Â°C for both x=0.19 and x=0.32.

Cd-rich mercury cadmium telluride (MCT) is a promising material for thin-film solar cell applications. In this letter we present data on the deposition of MCT films by a simple electroplating technique and report on the highest efficiency polycrystalline MCT thin-film solar cell to date, which...

Presents a study which focused on the results of the optical and electrical performance of P-on-n mercury cadmium telluride heterojunction photodiodes, with a linear gradient in composition. Material properties and electric field in the active region; Information on photocurrent and dark...

The second order nonlinear coefficient (d[sub 36]) of the narrow band gap semiconductor, mercury cadmium telluride (MCT), is measured. Because MCT is strongly absorbing at a 1.06 Î¼m wavelength, the measurement was performed by comparing the second harmonic intensity reflected from the...

A procedure is proposed for determining the stoichiometric composition of an intrinsic semiconductor Hg[sub 1-x]Cd[sub x]Te, relying upon the field effect in an electrolyte. An original comparative analysis of experimental capacitance-voltage characteristics and those calculated in terms of a...

We present an overview concerning the modification of properties of HgCdTe solid solutions and related Hg-containing materials under surface treatment with low-energy (60â€“2000 eV) ion beams. The conditions for conductivity-type conversion in p-material, dose, and time dependences of the...

Chaos in photovoltaic HgCdTe detectors irradiated by a low-power stable continuous-wave laser is found in our experiment. The detectors give a chaotic output in the laser irradiation power density range a little higher than their saturation threshold. Chaos is diagnosed by calculating the power...
